Problems solved by technology

[0002] With the rapid growth of video monitoring demand in the field of smart home security, cameras are becoming more and more popular. However, the monitoring equipment in the prior art is controlled by motors. Due to the limitation of mechanical friction, the rotation speed of the cameras is slow, and fast positioning cannot be achieved; at the same time The cameras in the prior art are equipped with locking and limit mechanisms when controlling the rotation angle, which cannot achieve 360-degree continuous rotation; and the current cameras are all powered by cables or batteries, and the cables supply the monitoring equipment. The reliance is too large to work independently, and the battery power supply leads to insufficient battery life of the monitoring equipment

Embodiment 1

[0021] Magnetic levitation cameras, such as figure 1 As shown, it includes a camera body 3 and a magnetic levitation base 9. The camera body 3 is provided with an upper magnet 4 whose axis is vertically downward. The magnetic levitation base 9 is provided with a lower magnet 6 with the same polarity as the upper magnet 4. The camera body 3 is suspended on the magnetic levitation base. 9 above;

[0022] The camera body 3 is provided with a plurality of horizontal magnetic posts 2, and the axial direction of the horizontal magnetic post 2 is perpendicular to the axial direction of the upper magnet 4. The magnetic levitation base 9 is provided with a plurality of horizontal coils 1 for attracting the horizontal magnetic post 2. The plane where the coil 1 is located is parallel to the plane where the horizontal magnetic column 2 is located. The vertical projection of the horizontal magnetic column 2 is located inside the horizontal coil 1. When the current in the horizontal coil 1...

Embodiment 2

[0032] The number of horizontal magnetic columns 2 and horizontal coils 1 is 6 and 8 respectively, and the number of vertical coils 7 is 6.

[0033] like Figure 5 As shown, when only the horizontal coil 101 and the solenoid level 105 are fed with the same magnitude of current, according to the "right-hand spiral rule", a magnetic field is generated around the horizontal coil 101 and the horizontal coil 105, so that the horizontal coil 101 and the horizontal coil 105 produces magnetic force to horizontal magnetic post 201 and horizontal magnetic post 204 respectively; Now gradually reduce the electric current in horizontal coil 101 and horizontal coil 105, and increase the electric current of horizontal coil 102 and horizontal coil 106, horizontal coil 102 and horizontal coil 106 generates magnetic force to the horizontal magnetic column 202 and the horizontal magnetic column 205 respectively, so that the horizontal magnetic column 202 and the horizontal magnetic column 205 ro...

Abstract

The invention relates to a video camera and discloses a magnetic suspension video camera. The magnetic suspension video camera is characterized in that a video camera body (3) is suspended above a magnetic suspension base (9); a plurality of horizontal magnetic columns (2) are arranged on the video camera body (3); a plurality of horizontal coils (1) used for attracting the horizontal magnetic columns (2) are arranged on the magnetic suspension base (9); when the current in the horizontal coils (1) changes, the horizontal magnetic columns (2) drive the video camera body (3) to rotate. The video camera adopts a magnetic suspension technology, so that the video camera body and the base are separated, the mechanical friction in the original video camera is eliminated, the rapid positioning is realized, and meanwhile, the video camera body and the base have no direct contact, so that the video camera body can freely and continuously rotate under the control of the external magnetic force; the video camera also adopts a wireless charging technology, so that limitation of wired power supply to the magnetic suspension application is eliminated, and the defect of non-persistent battery supply is made up.
